Why Renewal by Andersen

Arched wooden-framed mirror with grid design

  • Energy Efficiency - Superior thermal insulating properties helps your home stay warmer in winter and cooler in summer and can help you save money on your energy bills.

  • Strength & Durability - Twice as strong as vinyl, Fibrex® material means weathertight seals stay weathertight. Its durable nature means that it can stand up to even the most extreme temperature swings, maintaining its stability and rigidity in all climates.

  • Low Maintenance - Your Renewal by Andersen® windows are warranted not to flake, rust, blister, peel, crack, pit or corrode. And years down the road, they will be as easy to operate as the day they are installed.*

  • Beauty - The strength of Fibrex® material means narrower frames; narrower frames mean more glass—and more view. Plus, the extrusion process allows us to craft your windows to any shape—meaning you can match the architectural style of your home…or define a new look.

[*] Based on testing of 10 double-hung units per ASTM E2068, 20 years after installation.
